Launcher will run, but minecraft won't?

Okay so here's the problem. I got on my computer after using minecraft just fine, so i launch minecraft. The minecraft launcher comes up no problem. It goes to the Mojang window then minimizes. I can't open it up without using Ctrl+Alt+Del or F11. It then shows the frame of the minecraft window, but nothing appears. Have i hit 0fps? I can hear my sound when i click buttons, but i can't see anything. Does anyone know the problem?

I run on a 1900's laser computer, that's around a foot to a foot and a half thick. I usually get 6fps on mc, but with optifine 10. Lol, i don't know the problem, and i know this computer is so overwhelmingly sad haha.

If you know the problem can you tell me how to fix it or find a link that can?

Maybe it is caused by old drivers?

Try to dedicate more memory to minecraft or close all of your apps open. Or reboot
